// WHAT WE DO
Comprehensive repair of asynchronous electric motors
Elektropromremont LLC performs overhaul, medium, and routine repair of asynchronous electric motors of Ukrainian and foreign manufacture, regardless of design, year of manufacture, or technical condition.
Our production facilities allow us to carry out a full cycle of electric machine restoration — from technical diagnostics and fault detection to manufacturing components, rewinding, machining, rotor balancing, high-voltage testing, and equipment commissioning.
Every motor undergoes quality control in accordance with regulatory documentation requirements and is issued a full set of test protocols.

SEND DATA// REPAIR CYCLE
A visual repair cycle — from fault detection to testing
Every stage on the blueprint is a real shop-floor operation: diagnostics, disassembly, rewinding, modernization.
// REPAIR STAGES
The complete repair cycle of an electric machine
From initial fault detection and condition assessment to full motor restoration, balancing, machining, and final testing.
- 01Initial fault detection
- 02Winding removal
- 03Testing of stator and rotor active steel
- 04Manufacturing of components
- 05Winding restoration / rewinding
- 06Impregnation and heat treatment
- 07Machining
- 08Rotor balancing
- 09Final testing
// CAPABILITIES & CONTROL
Scope of work, testing and industries served
// SCOPE OF WORK
What the repair includes
Stator rewinding
Rotor rewinding
Shaft repair
Seat restoration
Bearing assemblies
Housings
End shields
Fans
Terminal boxes
Manufacturing of components
// TESTING & CONTROL
Four control points — from intake to handover
Incoming insulation-resistance check, component measurement, fault report.
Every operation is checked before moving on to the next stage.
No-load run-in with vibration and heating checks on every assembly.
High-voltage test up to 35 kV with turn-to-turn insulation control.
Once testing is complete, the Customer receives a protocol issued by a certified laboratory.
